     16The definition of $I_{max}$ in the literature varies. Hashimoto *et al* (1991)  
     17define it as

     20    I_{max} = \Lambda^3\Delta\rho^2 
     21     
     22whereas Meier & Strobl (1987) give  
     23 
     24.. math:: 
     25    I_{max} = V_z\Delta\rho^2 
     26     
     27where $V_z$ is the volume per monomer unit.
